The method includes receiving a first user selection of a first one of the indicators. The method includes bringing at least one of the additional windows to the foreground, moving the at least one of the additional windows across the graphical user interface to be in view of the graphical user interface, sending the first window and the secondary windows behind the at least one of the additional windows, and moving at least one of the first window and the secondary windows across the graphical user interface to be out of view of the graphical user interface.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 13/247,848, filed on Sep. 28, 2011, and entitled “Sliding Window Manager,” which claims the benefit of U.S. Provisional Application No. 61/504,683, filed on Jul. 5, 2011, and entitled “Sliding Window Manager,” the entire content of both of which applications are incorporate by reference herein.

TECHNICAL FIELD

This instant specification relates to window management in a graphical user interface.

BACKGROUND

Window-based graphical user interfaces generally include a window manager that controls the placement and appearance of interface windows for applications within a windowing system. In some cases, the window manager allows interface windows to be opened, closed, minimized, maximized, moved, and resized. In addition, the window manager often provides interface window decorators, such as a title bar or tab and/or a toolbar.

SUMMARY

In one aspect, a computer-implemented method for sliding based window management includes presenting a first window in a foreground of a graphical user interface. The method further includes presenting at least a portion of each of one or more secondary windows in the graphical user interface. The method further includes presenting one or more indicators in the graphical user interface indicating that additional windows exist. The method further includes receiving a first user selection of a first one of the indicators. The method further includes, in response to receiving the first user selection, bringing at least one of the additional windows to the foreground in the graphical user interface, moving the at least one of the additional windows across the graphical user interface to be in view of the graphical user interface, sending the first window and the secondary windows behind the at least one of the additional windows, and moving at least one of the first window and the secondary windows across the graphical user interface to be out of view of the graphical user interface.

Implementations can include any, all, or none of the following features. The method can include receiving a second user selection of one of the secondary windows and, in response to receiving the second user selection, bringing the selected one of the secondary windows to the foreground in the graphical user interface and sending the first window and others of the secondary windows behind the selected one of the secondary windows without moving the first window and the secondary windows across the graphical user interface. Each of the indicators can include a grayed or blurred portion of an associated one of the additional windows. The first window and the at least one of the additional windows can occupy less than a full width of the graphical user interface. Moving the additional window across the graphical user interface can include moving the additional window horizontally across the graphical user interface. Moving the at least one of the first window and the secondary windows across the graphical user interface can include moving the at least one of the first window and the secondary windows horizontally across the graphical user interface. The first window, the secondary windows, and the additional windows can be included in an ordered list of windows. Prior to receiving the first user selection, the first one of the indicators can indicate that one or more of the additional windows exist before the first window and the secondary windows in the ordered list of windows. A second one of the indicators can indicate that one or more of the additional windows exist after the first window and the secondary windows in the ordered list of windows. The method can include determining, in response to the first user selection, that none of the additional windows exist before the at least one of the additional windows in the ordered list of windows, and no longer presenting the first one of the indicators in response to determining that none of the additional windows exist before the at least one of the additional windows. Moving the at least one of the first window and the secondary windows across the graphical user interface can include moving a last one of the secondary windows across the graphical user interface to be out of view of the graphical user interface. The method can further include moving the first window and ones of the secondary windows other than the last one of the secondary windows across the graphical user interface with at least a portion of each remaining in view of the graphical user interface.

In one aspect, a computer-readable medium storing instructions that when executed cause a computer to perform operations for sliding based window management, where the operations include presenting a first window in a graphical user interface. The first window is active. The operations further include presenting at least a portion of each of one or more secondary windows in the graphical user interface. The secondary windows are not active. The operations further include presenting one or more indicators in the graphical user interface indicating that additional windows exist. The operations further include receiving a first user selection of a first one of the indicators. The operations further include, in response to receiving the first user selection, making at least one of the additional windows active in the graphical user interface, moving the at least one of the additional windows across the graphical user interface to be in view of the graphical user interface, making the first window and the secondary windows not active, and moving at least one of the first window and the secondary windows across the graphical user interface to be out of view of the graphical user interface.

Implementations can include any, all, or none of the following features. The operations can further include receiving a second user selection of one of the secondary windows and, in response to receiving the second user selection, making the selected one of the secondary windows active in the graphical user interface and making the first window and others of the secondary windows not active without moving the first window and the secondary windows across the graphical user interface. Each of the indicators can include a grayed or blurred portion of an associated one of the additional windows. The first window and the at least one of the additional windows can occupy less than a full width of the graphical user interface. Moving the additional window across the graphical user interface can include moving the additional window horizontally across the graphical user interface. Moving the at least one of the first window and the secondary windows across the graphical user interface can include moving the at least one of the first window and the secondary windows horizontally across the graphical user interface. The first window, the secondary windows, and the additional windows can be included in an ordered list of windows. Prior to receiving the first user selection, the first one of the indicators can indicate that one or more of the additional windows exist before the first window and the secondary windows in the ordered list of windows. A second one of the indicators can indicate that one or more of the additional windows exist after the first window and the secondary windows in the ordered list of windows. The operations can further include determining, in response to the first user selection, that none of the additional windows exist before the at least one of the additional windows in the ordered list of windows, and no longer presenting the first one of the indicators in response to determining that none of the additional windows exist before the at least one of the additional windows. Moving the at least one of the first window and the secondary windows across the graphical user interface can include moving a last one of the secondary windows across the graphical user interface to be out of view of the graphical user interface. The operations can further include moving the first window and ones of the secondary windows other than the last one of the secondary windows across the graphical user interface with at least a portion of each remaining in view of the graphical user interface.

In one aspect, a computer-implemented system for sliding based window management includes a display device that presents a graphical user interface that includes a first window, at least a portion of a second window, and one or more overflow indicators. The first window is active and the second window is not active. The overflow indicators indicate that additional windows exist that are not currently presented. The system further includes an interface that receives a first user input that selects a first one of the overflow indicators. The system further includes one or more processors that, in response to receiving the first user input, make at least one of the additional windows active in the graphical user interface, move the at least one of the additional windows across the graphical user interface to be in view of the graphical user interface, make the first window and the second window not active, move the first window across the graphical user interface with at least a portion of the first window remaining in view of the graphical user interface, and move the second window across the graphical user interface to be out of view of the graphical user interface.

Implementations can include any, all, or none of the following features. The interface can receive a second user input that selects the second window, and the processors, in response to receiving the second user input, can make the second window active in the graphical user interface, and make the first window not active without moving the first window and the second window across the graphical user interface. Each of the overflow indicators can include a grayed or blurred portion of an associated one of the additional windows. The first window and the at least one of the additional windows can occupy less than a full width of the graphical user interface. The processors can move the at least one of the additional windows, the first window, and the second window horizontally across the graphical user interface. The first window, the second window, and the additional windows can be included in an ordered list of windows. Prior to receiving the first user input, the first one of the overflow indicators can indicate that one or more of the additional windows exist before the first window and the second window in the ordered list of windows. A second one of the overflow indicators can indicate that one or more of the additional windows exist after the first window and the second window in the ordered list of windows. The processors can determine, in response to the first user input, that none of the additional windows exist before the at least one of the additional windows in the ordered list of windows, and no longer present the first one of the overflow indicators on the display device in response to determining that none of the additional windows exist before the at least one of the additional windows.

The details of one or more implementations are set forth in the accompanying drawings and the description below. Other features and advantages will be apparent from the description and drawings, and from the claims.

DETAILED DESCRIPTION

This document describes systems and techniques for managing windows in a graphical user interface using a sliding based metaphor. Conceptually, a window manager moves or navigates through a set of windows so that the windows appear to slide from side to side. In addition, the window manager can also use a stacking metaphor, so that moving through the set of windows appears to move up or down through the stack of windows. A particular number of windows are directly accessible on the currently viewed display screen (e.g., by staggering the display of portions of the stack of windows), and one or more other windows are accessible after sliding or shifting the stack of windows to the side to access one or more of the previously inaccessible windows.

The systems and techniques described here may provide one or more of the following advantages. First, a system can provide a reduction in processing at a central processing unit or graphics processing unit by restricting the directly accessible windows to a particular number of windows. Second, a system can provide quick navigation among a large number of windows.

FIG. 1 is a schematic diagram that shows an example of a system 100 for sliding based window management. Sliding window management can be implemented in one or more types of computing devices, such as a smartphone 102 a, a tablet computing device 102 b, a laptop or netbook computing device 102 c, and a desktop computing device 102 d. Each display screen of the computing devices has a viewing area 104. The viewing area 104 presents a graphical user interface that can include multiple windows 106.

Each computing device includes a window manager, which is an application or application program interface (API) that manages the placement of the windows 106 within the viewing area 104. For example, the window manager can determine which of the windows 106 are to be displayed at a particular point in time and which of the windows 106 are hidden or out the viewing area 104. The window manager can also move a window from outside the viewing area 104 into the viewing area 104 using a sliding based navigation.

The windows 106 are shown in FIG. 1 conceptually as whole windows in separate layers for ease of description. However, the actual representation of the windows on a display device may use another metaphor or internal representation. For example, the window manager can present a first window 106 a in a top or foreground layer. The first window 106 a is the active window or the window that a user is currently accessing. In some implementations, the first window 106 a is completely visible within the viewing area 104 of the display device. In some implementations, the first window 106 a occupies the full height of the viewing area 104 and less than the full width of the viewing area 104.

The window manager also presents a portion 108 of at least one secondary window 106 b at a lower layer than (e.g., behind) the first window 106 a. For example, the window manager can use a portion of the remainder of the width of the viewing area 104, after allotting horizontal viewing space to the first window 106 a, for the secondary window 106 b. In some implementations, the window manager staggers a stack of two or more windows so that the window manager displays at least one entire window and at least a portion of each of the other windows in the staggered stack. In some implementations, the portion 108 of the secondary window 106 b also occupies the full height of the viewing area 104. A user can select the portion 108 to request that the window manager bring the secondary window 106 b to the foreground and send the first window 106 a to a layer behind the secondary window 106 b.

The window manager also presents at least one indicator 110 on the display device when at least one additional window 106 c exists that is currently outside or not displayed within the viewing area 104. The indicator 110 is a visual cue that the additional window 106 c exists and at least a portion of which is currently outside or not displayed within the viewing area 104. In some implementations, the window manager includes a small grayed and/or blurred out portion of the additional window 106 c in the indicator 110. A user can select the indicator 110 to request that the window manager bring the additional window 106 c to the foreground and slide the additional window 106 c into the viewing area 104. As a result, the sliding of the additional window 106 c brings a portion 112 of the additional window 106 c that was previously outside the viewing area 104 into the viewing area 104.

Accordingly, the window manager also slides one or more of the windows currently in the viewing area 104 out of the viewing area 104, such as the first window 106 a. For example, the window manager can slide a portion 114 of the first window 106 a outside the viewing area by the same amount that the additional window 106 c was previously outside the viewing area 104. In addition, the window manager can also slide one or more of the windows currently in the viewing area 104 to the side of the viewing area 104, such as the secondary window 106 b. For example, the window manager can slide the secondary window 106 b to the side of the viewing area 104 so that a portion 116 of the secondary window 106 b is visible from behind the additional window 106 c within the viewing area 104.

In some implementations, the window manager presents a small grayed out and/or blurred portion of the first window 106 a in an indicator 118. A user can select the indicator 118 to request that the window manager bring the first window 106 a to the foreground and slide the first window 106 a back into the viewing area 104 again.

FIG. 2A shows an example of a graphical user interface (GUI) 200 for sliding based window management. The GUI 200 includes a viewing area 202 (indicated by the bold line in FIG. 2A) that is presented on a display device of a computing device. A window manager that presents windows within the viewing area 202 currently manages a first window 204 a, a second window 204 b, a third window 204 c, and a fourth window 204 d. The second window 204 b is currently active and displayed in the foreground within the viewing area 202. The window manager presents the third window 204 c at a lower layer than the second window 204 b. Accordingly, the window manager presents only a portion of the third window 204 c in the viewing area 202.

The first window 204 a and the fourth window 204 d are not currently presented in the viewing area 202. In some implementations, the window manager is configured to present a particular number of windows within the viewing area 202, such as two (as shown in FIG. 2A) or another number of windows. The window manager presents one or more indicators 206 a-b within the viewing area 202. The indicators 206 a-b indicate to the user that one or more windows are currently not being presented within the viewing area 202. In particular, the indicator 206 a indicates that one or more windows exist, that are not currently displayed, to the left of or above the second window 204 b in a conceptual stack of windows. The indicator 206 b indicates that one or more windows exist, that are not currently displayed, to the right of or below the third window 204 c in the conceptual stack of windows.

In some implementations, the indicators 206 a-b can include a representation of the contents of the first window 204 a and the fourth window 204 d, respectively. For example, the window manager can show a grayed and/or blurred out portion of the first window 204 a and the fourth window 204 d in the indicators 206 a-b, respectively.

A user can make a request to the window manager to switch to a displayed window, such as the third window 204 c, by selecting the displayed window. For example, the user can select a window portion using a pointing device 208, such as is provided by a mouse, trackball, touchpad, or touch screen. In another example, the user can select a window portion using keyboard inputs, such as arrow keys.

FIG. 2B shows an example of a GUI 210 after switching to another window that was previously displayed. In response to the user selection of the third window 204 c, the window manager brings the third window 204 c to the foreground. In addition, the window manager moves the second window 204 b behind the third window 204 c and as a result, only a portion of the second window 204 b is currently displayed in the viewing area 202. The first window 204 a and the fourth window 204 d remain out of the viewing area 202 as indicated by the indicators 206 a-b. A user can select one of the indicators 206 a-b, such as the indicator 206 b on the right side of the viewing area 202, to make a request to window manager to bring one or more other windows into the viewing area 202.

FIG. 2C shows an example of a GUI 212 after switching to another window that was previously outside the viewing area 202. In response to the user selection of the indicator 206 b, the window manager brings the fourth window 204 d to the foreground. In addition, the window manager places the third window 204 c and the second window 204 b behind the fourth window 204 d. As a result, the window manager only presents a portion of each of the third window 204 c and the second window 204 b.

In some implementations, the window manager maintains an initial ordering of the windows after bringing the fourth window 204 d to the foreground. For example, the window manager places the second window 204 b behind the third window 204 c, which the window manager places behind the fourth window 204 d. In some implementations, the window manager grays or blurs out the portion of the second window 204 b indicating that the second window 204 b will be moved outside the viewing area 202.

FIG. 2D shows an example of a GUI 214 after sliding a window into the viewing area that previously had a portion that was outside the viewing area 202. After bringing the fourth window 204 d to the foreground, the window manager slides the fourth window 204 d into the viewing area 202. The sliding motion can be animated so that the window manager can provide the user with a smooth visual transition from the original position of the fourth window 204 d to the final position within the viewing area 202.

The window manger also slides the third window 204 c to the left within the viewing area 202. The window manager gradually slides the second window 204 b to the left until the second window 204 b is no longer presented within the viewing area 202. The window manager no longer presents the indicator 206 b, as there are no additional windows to the right of or above the fourth window 204 d. In addition, the window manager continues to present the indicator 206 a, which indicates that one or more windows exist, that are currently not displayed, to the left of or below the third window 204 c.

In some implementations, the window manager can slide the indicator 206 a off the viewing area 202 along with the second window 204 b and present another indicator along the left edge of the viewing area 202. For example, the indicator 206 a may include a grayed and/or blurred out portion of the first window 204 a that the window manager slides to the left out of the viewing area 202 as the window manager slides the portion of the second window 204 b into the space previously occupied by the indicator 206 a. The window manager can then use a portion of the second window 204 b that remains within the viewing area 202 as the new indicator. The user can select the indicator 206 a to make a request to the window manager to display the next window to the left of or above the third window 204 c in the stack of windows.

FIG. 2E shows an example of a GUI 216 after switching to another window that was previously outside the viewing area 202. In response to the user selection of the indicator 206 a, the window manager brings the next window in the stack to the foreground (e.g., the second window 204 b). Accordingly, the window manager sends the third window 204 c and the fourth window 204 d behind the second window 204 b. While the second window 204 b is currently the foreground window, a portion 218 of the second window 204 b remains outside the viewing area 202.

FIG. 2F shows an example of a GUI 220 after sliding a window into the viewing area that previously had a portion that was outside the viewing area 202. In particular, the window manager slides the second window 204 b into the viewing area 202. In addition, the window manager slides the third window 204 c to the right and slides the fourth window 204 d out of the viewing area 202. The window manager also recreates the indicators 206 a-b for the first window 204 a and the fourth window 204 d, respectively.

As previously described, while these examples show two windows as being currently displayed within the viewing area 202, another number of windows can be displayed within the viewing area 202. For example, in the case of three or more windows, the window manager presents a full window and at least a portion of each of two or more other windows. In this example, the window manager can place one or more portions to the left of the foreground window and one or more portions to the right of the foreground window. In some implementations, each of the three or more windows occupies the full height of the viewing area 202.

In some implementations, the window manager minimizes disruption to the user by maintaining the positions of the currently displayed windows within the viewing area 202. For example, as a user selects a portion of a displayed window that is not currently the foreground window, the window manager brings the selected window to the foreground without changing the horizontal position of the selected window or the horizontal position of the other displayed windows.

However, in response to selecting one of the indicators 206 a-b, the window manager does change the horizontal position of the windows while bringing at least one other window into the viewing area 202. In some implementations, the window manager brings multiple other windows into the viewing area 202 in response to a user selection of one of the indicators 206 a-b. For example, the window manager can shift the windows left or right by a particular number of windows, such as two or three, in response to a user selection of one of the indicators 206 a-b.

FIG. 3 is a flow chart that shows an example of a process 300 for sliding based window management. The process 300 may be performed, for example, by a system such as the system 100. For clarity of presentation, the description that follows uses the system 100 as an example for describing the process 300. However, another system, or combination of systems, may be used to perform the process 300.

The process 300 begins with presenting (302) a first window, at least a portion of each of one or more secondary windows, and one or more indicators in a graphical user interface. The first window is active and/or is in the foreground of the graphical user interface. The secondary windows are not active and/or are in the background of the graphical user interface. The indicators indicate that additional windows exist that may not be currently displayed. In some implementations, the indicators each include a small grayed out or blurred portion of an associated one of the additional windows. In some implementations, the GUI continuously updates content within the first window and the portions of the secondary windows and the small grayed out or blurred portions of the additional windows in the indicators are not continuously updated.

The process 300 receives (304) a user input that selects either one of the secondary windows or one of the indicators. For example, the tablet computing device 102 b can receive a user input that selects the portion 108 of the secondary window 106 b or the indicator 110 that is associated with the additional window 106 c.

In response to receiving the user input that selects one of the secondary windows, the process 300 activates (306) the selected secondary window. For example, the tablet computing device 102 b can bring the secondary window 106 b to a foreground layer in front other windows in the viewing area 104 and/or make the secondary window 106 b active within the viewing area 104. Being active refers to accepting user inputs or interactions within a window other than a user input that makes the window active.

Also in response to receiving the user input that selects one of the secondary windows, the process 300 deactivates (308) a previously active and/or foreground window (e.g., the first window). The process 300 performs the deactivation of the first window and activation of the secondary window without moving the first window and the secondary window across the graphical user interface. The lack of movement across the graphical user interface prevents any noticeable change in a horizontal and/or vertical position of the first window and the secondary window. For example, the tablet computing device 102 b can send the first window 106 a to a layer that is behind the secondary window 106 b in the viewing area 104 and/or make the first window 106 a inactive within the viewing area 104. The process 300 can then receive (304) further user inputs, such as the user input that selects one of the indicators.

In response to receiving the user input that selects one of the indicators, the process 300 activates (310) an additional window that is associated with the selected one of the indicators. For example, the tablet computing device 102 b can bring the additional window 106 c to a foreground layer in front other windows in the viewing area 104 and/or make the additional window 106 c active within the viewing area 104.

Also in response to receiving the user input that selects one of the indicators, the process 300 deactivates (312) the first window and the secondary windows. For example, the tablet computing device 102 b can send the first window 106 a and the secondary window 106 b to a layer that is behind the additional window 106 c in the viewing area 104, and/or make the first window 106 a and the secondary window 106 b inactive within the viewing area 104.

The process 300 moves (314) the additional window across the graphical user interface so that the additional window is in view of the graphical user interface. The process 300 also moves (314) at least one of the first window and the secondary windows across the graphical user interface so that the at least one of the first window and the secondary windows is out of view of the graphical user interface. Out of view can include, in some implementations, displaying a small portion of an out of view window within one of the indicators. The small portion can be large enough to be selected with a pointing device, but small enough so as to be unobtrusive to the user and/or occupy a minimal amount of display space within the graphical user interface.

For example, the tablet computing device 102 b can move the additional window 106 c across the viewing area 104 so that the portion 112 is within the viewing area 104. The tablet computing device 102 b also moves the first window 106 a and the secondary window 106 b across the viewing area 104 so that the first window 106 a is out of the viewing area 104 (e.g., the portion 114 is outside the viewing area 104 and the remainder of the first window 106 a is behind the secondary window 106 b and the additional window 106 c with the exception of a small portion that may be presented within the indicator 118.

If one or more additional windows exist that are out of view of the graphical user interface (316), then the process 300 presents (318) one or more indicators associated with the additional windows. For example, the tablet computing device 102 b can present the indicator 110 associated with the additional window 106 c and the indicator 118 associated with the first window 106 a. The process 300 can then receive (304) further user inputs again that select secondary windows and/or indicators.

In some implementations, the windows are conceptually arranged in an ordered list or stack. Presenting indicators can include determining that one or more out of view windows exist in the list ahead of the currently presented windows, and presenting a corresponding indicator on a first side of the graphical user interface. Presenting indicators can further include determining that one or more out of view windows exist in the list after the currently presented windows, and presenting a corresponding indicator on a second side of the graphical user interface. If no indicators exist ahead of and/or after the currently presented windows, then the corresponding indicator is not presented.

In some implementations, the order of the operations in the process 300 can be performed in an order other than the order described here. For example, the steps of activating windows and deactivating windows can be performed at the same time, concurrently, or in either order. In another example, the steps of moving windows and activating/deactivating windows can also be performed at the same time, concurrently, or in either order.

FIG. 4 is a schematic diagram that shows an example of a computing device 400 and an example of a mobile computing device that can be used to implement the systems and techniques described here. The computing device 400 is intended to represent various forms of digital computers, such as laptops, desktops, workstations, personal digital assistants, servers, blade servers, mainframes, and other appropriate computers. The mobile computing device is intended to represent various forms of mobile devices, such as personal digital assistants, cellular telephones, smartphones, and other similar computing devices. The components shown here, their connections and relationships, and their functions, are meant to be exemplary only, and are not meant to limit implementations of the inventions described and/or claimed in this document.

The computing device 400 includes a processor 402, a memory 404, a storage device 406, a high-speed interface 408 connecting to the memory 404 and multiple high-speed expansion ports 410, and a low-speed interface 412 connecting to a low-speed expansion port 414 and the storage device 406. Each of the processor 402, the memory 404, the storage device 406, the high-speed interface 408, the high-speed expansion ports 410, and the low-speed interface 412, are interconnected using various busses, and may be mounted on a common motherboard or in other manners as appropriate. The processor 402 can process instructions for execution within the computing device 400, including instructions stored in the memory 404 or on the storage device 406 to display graphical information for a GUI on an external input/output device, such as a display 416 coupled to the high-speed interface 408. In other implementations, multiple processors and/or multiple buses may be used, as appropriate, along with multiple memories and types of memory. In addition, multiple computing devices may be connected, with each device providing portions of the necessary operations (e.g., as a server bank, a group of blade servers, or a multi-processor system).

The memory 404 stores information within the computing device 400. In some implementations, the memory 404 is a volatile memory unit or units. In some implementations, the memory 404 is a non-volatile memory unit or units. The memory 404 may also be another form of computer-readable medium, such as a magnetic or optical disk.

The storage device 406 is capable of providing mass storage for the computing device 400. In some implementations, the storage device 406 may be or contain a computer-readable medium, such as a floppy disk device, a hard disk device, an optical disk device, or a tape device, a flash memory or other similar solid state memory device, or an array of devices, including devices in a storage area network or other configurations.

The high-speed interface 408 manages bandwidth-intensive operations for the computing device 400, while the low-speed interface 412 manages lower bandwidth-intensive operations. Such allocation of functions is exemplary only. In some implementations, the high-speed interface 408 is coupled to the memory 404, the display 416 (e.g., through a graphics processor or accelerator), and to the high-speed expansion ports 410, which may accept various expansion cards (not shown). In the implementation, the low-speed interface 412 is coupled to the storage device 406 and the low-speed expansion port 414. The low-speed expansion port 414, which may include various communication ports (e.g., USB, Bluetooth, Ethernet, wireless Ethernet) may be coupled to one or more input/output devices, such as a keyboard, a pointing device, a scanner, or a networking device such as a switch or router, e.g., through a network adapter.

The computing device 400 may be implemented in a number of different forms, as shown in the figure. For example, it may be implemented as a standard server 418, or multiple times in a group of such servers. In addition, it may be implemented in a personal computer such as a laptop computer 420.

The external interface 462 may provide, for example, for wired communication in some implementations, or for wireless communication in other implementations, and multiple interfaces may also be used.

The memory 464 stores information within the mobile computing device 450. The memory 464 can be implemented as one or more of a computer-readable medium or media, a volatile memory unit or units, or a non-volatile memory unit or units. The memory 464 may include, for example, flash memory and/or NVRAM memory (non-volatile random access memory).

An expansion memory 474 may also be provided and connected to the mobile computing device 450 through an expansion interface 472, which may include, for example, a SIMM (Single In Line Memory Module) card interface.

Such communication may occur, for example, through the transceiver 468 using a radio-frequency. In addition, short-range communication may occur, such as using a Bluetooth, Wi-Fi, or other such transceiver (not shown). In addition, a GPS (Global Positioning System) receiver module 470 may provide additional navigation- and location-related wireless data to the mobile computing device 450, which may be used as appropriate by applications running on the mobile computing device 450.

The mobile computing device 450 may also communicate audibly using an audio codec 460, which may receive spoken information from a user and convert it to usable digital information. The audio codec 460 may likewise generate audible sound for a user, such as through a speaker, e.g., in a handset of the mobile computing device 450. Such sound may include sound from voice telephone calls, may include recorded sound (e.g., voice messages, music files, etc.) and may also include sound generated by applications operating on the mobile computing device 450.

The mobile computing device 450 may be implemented in a number of different forms, as shown in the figure. For example, it may be implemented as a cellular telephone 480. It may also be implemented as part of a smartphone 482, personal digital assistant, or other similar mobile device.
